TREATMENT on iaan'nsn mrnuiamm N0 Brewing.

T0 all whom it may concern Be it known that I, lnosri-iu Juan AU- ons'rn lllaumnn, a citizen of France, rcsiding at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have inrented a certain new and useful lmprorement in the Treatment of Manure, whereof the following is a sgecitication.

1t the object of my invcnthin to preserve the fertilizing value ol organic pr0ducts,.of vegetable or animal origin, including stable and barn-yard manure, green crops, sea weeds, meat, lish or other refuse liable to "fermentation or putreliaction. Said substances are not directly available as ilertilizcrs, but must uni[ergo transfornmtion by 111l(l'(70l'Q2!IllSHlS, before they can be utilized as plant food. Such transhn'mation manifested by fermentation or putreliu-tion oi said substances during which part of the organic nitrogen is transi'iorined into free ammonia which, when said substances are not in the soil. escapes into the atmosphere, and a. part oi said substances which is transformed into nitrates which, when not in the soil, may be lost by leaching and weathering; so that. the. loss of fertilizing values may amount to fifty or sixty per cent, if no preventive means are employed. l" heold process of making coinposts is intem'led toprevent such loss by causing); the gases, and other tertilizii'ig products set tree by formentation, to be absorbed by peat, earth, or other inert absorbing material.

I ha ve discovered that the fertilizing alues of such organic products may be preserved without the. employment of inert absorbing material, by causing the activity oil the microorganisms to is suspended until such time as it is desired to employ said substances Fertilizers. Such tempo ai stel ilizcation of said organic. matter is conveniently ctl'ectcd by subjecting the same to one or more maccrations in an aqueous alkaline solution. Such solutions are preferably formed of sodalimc, or about equal parts of line and soda, of strength which may be varied to suit the particular kind. of sub Specification of Letters Patent.

stance to be treat-ed, so that the activity oi" the microorganisms is thereby checked. and suspended and the original soluble organic and inorganic substances are chemically tran formed into new. combinations. l or instance, a solution containing about one per cent. of said compounds of calcium and sodium may be employed. The product of the Patent-ell Polar. flit,

macerated cold, but others are preferably warmed. and the decree of heat is to be regulated in accordance with the particular kind of material under treatment. "When heat is used, I find it preferable to a pply the, same for a given time and then withdraw it: so that while the tennnurature is raised, air is driven off from the materialundcr treatment and during: the subsequent cooling, the solvent lllif-Mrlllttl into the pores of the ma terial. in some cases, a single maceration. is s'n'llicieut, but some substances may advanta'g'eously be subjected to several maccrations, either with the same solution or vith fresh solutions, of such strength as the ture of the material. requires.

"When the process of temporary stcriliza-- tion, above described, is completed; the product may turthcr treated either by drying the solute and the solid together, or by separating the solute from the solid, either by draining or othc "e, and m orating" or drying); them separately; the fluid solute being preferably coi'iccntratcd to the consistency of a paste or solid. Such conceutration is of commercial advantage in that the fertilifai'ng material is thus reduced to minimum bulk and weight sot-h. storage or transportation thereof 1 s3 be effected. more economically than in the original not 11 'al. condition.

It may he observed that untreated mm nurcs are capable of convc 'ng; infections diseases to man, beast or plant; may carry seeds of woods, or injurioiiis biological or chemical products; may become hctf fire fanned, or otherwise deteriorate, and. are

not applicable to all crops. Treatment in accordance with my invention eliminates all oi said objectionable features and atl'ords a n'oduct which in rant, acts directly as a fertilizer, hecause it is soluble in Water; and the renniindsr sustains the action of the r when in the ground 01' All we ie is oi'aiy sterilization or suspension a i'ly in?
